You should not omit the specialization to wage wars everywhere else in the world and stirring in everyone else's soup. 

This is a logical fallacy, a "false dichotomy". There are situations other than "respect government" and a "lawless state". The fact that the US exists proves the existence.
No, my point is that the disagreement with elected authority dates to the earliest days of the Republic. It is not anything new at all. It is present throughout US history from earliest time to the present. Before the US existed, it also existed in British history. The English speaking peoples have never been ones to keep their mouths shut about government they disagree with. And I should note that the US has been totally free of military dictatorship these 239 years and this applies in peacetime as well as wartime. Britain has also been free of military dictatorship for an even longer time. History shows that we are the world experts on maintaining long-lived more or less fair rule of law and elections, certainly not Germany.
First, this is a mysterious change of subject for a purpose unknown. Second, it is patently false. Slavery was dying away all over the new world and would have died away in the South probably before mechanized farming made it obsolete. Slavery was originally present throughout the US; it was decreasing faster in the North than the South. You might as well say that the US would never have gay marriage except for the recent Supreme Court ruling. Or that we would have never have had an equivalent to the Environmental Protection Agency except that Nixon signed it into law by presidential decree.
Saying that the south would still have had slavery in 2015 without the existence of a war in 1861 is as stupid as saying that Germany would still be ruled by Nazis if it were not for a war in 1937. No. Again, your logical failure is one of "false dichotomy". The world is more complicated than that. Things change whether there is war or not. Franco's fascist regime in Spain ended without any war. And the USSR fell with no war involved. If there had been no war, the Nazis would probably have slowly mellowed out similar to Franco's Spain, or Stalin's USSR, and Germany would have eventually evolved to be something not too different from what it is now. People find excuses for war because they cannot otherwise accept the sadness of the death and destruction.
